The U.N. nuclear agency says it now expects nuclear power to grow more slowly than before the Fukushima nuclear disaster.
Hans Holger Rogner of the International Atomic Energy Agency says that the number of nuclear reactors in use by 2030 will increase by anywhere from 90 to 350 from the present 432.
He said Tuesday that the agency's high projection foresees nuclear power accounting for 13.5 percent of total energy generation in 2050. Its low projection forecasts a nuclear share of 6.2 percent by then.
That compares with projections last year _ before the Fukushima accident _ of 17 percent and 7.1 percent in 2050.
Those figures reflect expectations that power generation will increase overall and that nuclear power could lose ground to other energy sources.
